Work items:
* Removed the globale-requirements constraint. Since python-cloudkittyclient
is now part of the global requirements, the upstream requirements
file can't be used anymore.
* Add cliff to docs requirements.
* Change cloudkittyclient namespace names: Having a dot in a namespace
name causes the "autoprogram-cliff" to use the "application mode".
